Abstract
Real-time location system and method, the system including a tag and a plurality of groups, each group including: a plurality of battery operated secondary technology base-stations, and a battery operated wireless timing beacon generator to provide a timing beacon to the group, such that the timing beacon generator for a group obtains timing information for the timing beacon wirelessly from a timing server, and such that each timing beacon generator transmits timing beacons with timing information to the plurality of base-stations in the group, and each secondary technology base-station transmits a secondary technology signal to the tag based on the received timing beacon.
Claims20
A real-time location system comprising:
- a tag and a plurality of groups, each group comprising:
- a plurality of battery operated secondary technology base-stations;
- and
- a battery operated wireless timing beacon generator to provide a timing beacon to the group,
- wherein the timing beacon generator for a group obtains timing information for the timing beacon wirelessly from a timing server, and
- wherein each timing beacon generator transmits timing beacons with timing information to the plurality of base-stations in the group, and each secondary technology base-station transmits a secondary technology signal to the tag based on the received timing beacon.
A method to provide timing information to a tag in a real-time location system, the method comprising:
- wirelessly obtaining, by a timing beacon generator, timing information from a timing server;
- transmitting, by the timing beacon generator, a timing beacon to a plurality of battery operated secondary technology base-stations, wherein the timing beacon generator transmits its timing beacon at a different time than other timing beacons in order to avoid collisions with other timing beacons;
- transmitting, by the secondary technology base-stations, a respective secondary technology signal based on the received timing beacon.
